Looking for a Simple Doubly Linked List Implementation

[Ron Tarrant via Digitalmars-d-learn]

Hi guys,

I've been banging my head on the screen with this one for the 
last week or so. For whatever reason, I'm having major problems 
understanding how to implement a doubly-linked list in D. I don't 
know if it's because I'm losing my ability to sort these things 
or if it's just that different from C.

If someone could please post a minimal example (if there's extra 
stuff in there, I'll get confused; I'm getting that old, dammit) 
I'd be ever so grateful.
